Some people like tp browse the product catalogue, some people only want to see what's in stock. We created this tab for the latter group. What is in stock is current each morning, adjusted for sales that happened in the day. If we run out, the inventory will let you know, the puzzle will be removed from in stock status the following day or sooner. Inventory is always in flux so it can change its status.
We hope this helps out those who just want to see what's available to ship now.
